Specification of Letters Patent.

Application filed July 19, 1920. Serial No. 397,335.

To all whom it may concern:

Be it known that 1, JAMES TOSCAN, a citizen of the United States, residing at the city of Jamestown, in the county of Chauand reheating of the hot products of combustion from the burning gas; and the invention consists in the novel features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is a vertical sectional view of the so-called pipeless heating stove type of gas heater showing the construction and arrangement of the combustion chamber and the different chambers within said gas heating stove. Fig. 2 is a perspective sectional view of the two outer cylinders with the inner short cylinder in full perspective showing the flanged rim on the ring plate at the bottom of said short *cylinder; and Fig. 3 is a perspective view of the under side of the stove showing the arrangement of the same. Fig. 4 is a detail perspectiveview of the ring plate at the bottom of the short cylinder. Fig. 5 is a vertical sectional View showing the construction and arrangement of the pipeless furnace type of my gas burning heater; and Fig. 6 1S a horizontal sectional view of the same at line 66 in Fig. 5 showing the cen-v tral-opening in the cut-off ring plate at the lower end of the central short heating chamber, and the inlet and exit openings for the cold-and hot air in the top plate of said heater. Fig. 7 is a detail of one of the supporting brackets for said short cylinder and cut-off plate. Fig. 8 is a perspective view of register for said furnace type of gas heater. Fig. 9 is a fragmentary sectional view of the simplest form of my gas heating stove with one outer full length cylinder and the short concentrically spaced inner cylinder to provide the central heating chamber.

. Like characters of reference refer to corresponding parts in the several views.

The numeral 10 designates the cast metal base. for the stove type of gas burning heater, which base is provided with suitable legs to raise the base a spaced distance above the floor to receive air from beneath the same.

7 The stove type of gas heater has the cast metal top 11, which has downward flanges on the under side, thereof to retain the sheet metal cylinders 12, 13 and 14 in spaced concentric arrangement, the two cylinders 12 and 13 being full length, that is, extending from thetop 1-1 to the base 10 and the short cylinder 14 extends down part way and is supported upon the ring plate 15, which is in turn supported upon the brackets 16 which rest upon the base plate 10, though said plate 15 may be supported upon the annular inwardly bent sheet metal projection or shoulder 17 or upon both said projectionol? and the brackets 16 to hold said ring plate 15 and the short cylinder 14 firmly inposition.

The base plate 10 and the top plate 11 with the sheet metal cylinders 12, 13 and 14 therebetween are held firmly in position by means of the rods or bolts 18 which extend from the top plate 11 through the base 10 thereby securely holding all the parts. The outer cylinder12has an opening therethrough with a tube 19 which extends through the similar opening in the cylinder 13, thereby giving an opening into the combustion chamber 33, which has theburner 26 at the bottom of the same and supported in an opening 37 in the bottom plate 10, and the round opening 27 in the cut-off plate 15 at the top of said combustion chamber 33 opening into the heating chamber 36 within the short tubular cylinder 14.

p The outer cylinder 12 has the openings 20 around the bottom of the same which act as inlets for air. The short cylinder 14 has a series of-openings .21 near its lower end to receive any unheated air therethrough upon starting, and a series of outwardly bent lugs 23 around the top which form spacing lugs to hold the same firmly in position and at the same time provide the openings 22 through which the heated air or hot products of combustion escape. Any unheated air will descend and pass through the holes 21 to be reheated and then again ascend. and pass out through the openings 22 and through a series of openings 25 in the sheet metal cylinder 13 near the top of said cylinder. This takes placeupon starting, since the heat from'the burner moving past the openings 21, will tend to create a somewhat vacuous condition in the space between the cylinders 13 and 14, drawing any cold air in the top 30 andthe bottom 31 by additional flanges therein to provide for drawing thecold air from the apartment through the register 3-1 and the holes 35 in the top 30, drawing the same downward through the openings 20 as shown by the arrows, and thence upward and out through the holes 28 heating the air as it ascends. A portion of air is drawn in through the door 19 into the combustion chamber 33 and sent up wardinto the chamber 36 and outward through the openings 22 and down to either reenter the chamber 36 through the holes 31 and again be carried upward and out through the openings 25 and thence up through the openings 28 into the apartment, or to go directly out through said holes 25 and 28. into the apartment.

The register 34 is attached to the bottom 31 by means of bolts 32, thereby holding all the parts firmly in position and supporting the gas .turnace beneath said register 34.

It is apparent that my gas heater can be adapted to the desired use, thus in the simplest form of heating stove shown in Fig.9, only one full length outer cylinder is provided with the cut-off ring 15 supporting the lower end of the short inner cylinder 14c which. provides the inner heating chamber 36. This makes an economical small pipeless heating gas stove of good capacity. hen it is desired to increase this heating capacity, the additional spaced cylinder 12 is added. This is the form of stove more generally used, since it adds a larger confined circulation and consequent radiation for the heat.

In the furnace type shown in Figs. 5 and 6. the additional spaced cylinder 29 is provided, thereby providing means for drawing the air from the apartment down into the furnace and sending same outheated as shown and described. All of the different forms retain the combustion chamber 33 and heating chamber 36 with the short circulating chamber between the spaced cylinders 13 and 1 1 to assist in the thorough heating of the air and the radiation of the same.

I claim as new:

1. A gas stove comprising top and bottom plates, a cylinder clamped therebetween and formed intermediate its length with an internal shoulder, a ring plate seated on the openings adjacent its upper and lower ends in open communication with the space between said cylinders whereby the unheated gases issuing from the upper openings may reenter the lower openings.

2. A gas stove comprising top and bottom 7 plates, a cylinder clamped therebetween and formed intermediate its length with an internal shoulder, a ring plate seated on the shoulder and defining the upper wall of a combustion chamber, and a shorter cylinder of sheet metal supported on the ring plate and having its upper end engaged with the top plate and formed with a plurality of openings, and lugs integral with the shorter cylinder and extending outwardly therefrom at one of the edges of the openings to space the cylinders. V

3. In a gas stove, a top and a bottom plate, an outer cylinder clamped between the plates and having an interior shoulder, a ring-like plate seated on the shoulder, a shorter cylinder seated at one end on said plate and engaged at its opposite end with the top plate, said shorter cylinder having a series of openings, andlugs integral with the shorter cylinder and extending outwardly therefrom at the bottom edges of the openings to engage the outer cylinder to thereby hold the cylinders spaced, said openings effecting communication between the cylinders, and brackets secured at their upper ends to the ring-like plate and secured with each other through the space between the cylinders, and a'burner in the outer cylinder beneath the ring-like plate.

In testimony whereof I have afiixed my signature in the presence of two witnesses.

JAMES E. TOSOAN.
